Bio:Known as Jason B. Lee, a name likely an alias, Snake-Eater's identity is known to very few. After graduating Ranger School and becoming a Green Beret, he began working counter-intelligence. He was later assigned to the Phoenix Guard. While General Rey noted his great skill in the field, he also considered him unpleasant to be around and observed him to be brutal, cruel and bitter. He usually only spoke to complain or insult someone.

Cobra Commander infiltrated the White House, replacing and posing as Chief of Staff Garret Freedlowe. Working closely with the President, "Freedlowe" created a new team called the Phoenix Guard, which he intended to use to destroy and take the place of G.I. Joe. The team's roster was made up of former Cobra agents using false identities. Firefly joined the group in the guise of a soldier code-named Snake-Eater. The Phoenix Guard's commander General Rey was unaware of his soldiers'true identities, and lead them on a raid of the new Joe team's headquarters. Against his wishes, the team relied too easily on deadly force, injuring many Joes and killing many of their support staff. The Joes soon defeated the Phoenix Guard, arresting all its members except for Firefly who found General Colton, Scarlett and Kamakura in the wilderness outside the base. Firefly nearly shot Colton, but was forced to flee when reinforcements arrived. His current whereabouts are unknown.
